MITRE ATT&CK

T1059.001 PowerShell

The PDF file triggered critical heuristics for JavaScript actions and embedded JS streams. ClamAV also detected the file as Win.Trojan.Agent-36166, and this detection was confirmed on an extracted artifact. The presence of JavaScript suggests an attempt to execute malicious code, likely for downloading further payloads or exploiting vulnerabilities.

Heuristics 4

ClamAV: Win.Trojan.Agent-36166 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Win.Trojan.Agent-36166
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
